Former Firefly stars Jewel Staite (Kaylee) and Sean Maher (Simon) will reunite on an episode in the second season of the Syfy show Warehouse 13 .
The episode, called “Mild Mannered” will air in July in the States. Maher will play Sheldon, a quiet unassuming guy whose exposure to a dangerous object brings about shocking physical change. Staite will play Loretta, the object of his unrequited love.
During its first season, Warehouse 13 became the most-watched original drama series in Syfy/Sci-Fi’s history.
